wi/tweowo ROBERT DUESING, OF (JI-IICAGQ, ILLINOIB.

CARPET-RENOVATOR.

To all (Iv/mm, it nmy con/corn. Be it known that I, ROBERT H'. DUESING,

a citizen. of the United States, residing at,

Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carpet-Renovators and I do declare the following to be a full, clear,

and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in devices or mechanisms for removing dust and dirt from carpets and othercovers while on a floor or other surface.

The object of the invention is to improve and simplify the construction and operation of devices of this character and thereby render the same more efficient. Another object of the invention is to provide a device of this character in which two or more opposing air blasts or jets will. be directed toward or acrosseach other, so as to effectively remove dust from carpets, vel vets, furs, and the like having a nap surf-ace. l/Vith the above and other objects in view my invention consists in certain novel features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspectiveview of my improved carpet- Fig. 2 is a vertical longitudinal sectional view through the same. Fig. 3 is a vertical transverse sectional view. Fig. .4 is

a horizontal sectional view taken on the line 4 4 in Fig. 2; and Fig. 5 is a perspective view of one of the air-discharge nozzles, parts being broken away to more clearly illustratethe construction.

Referring to the drawings by numeral, m v improved dusting or renovating device,

7 which is ada 'ted to be moved over the surface to be c eaned, has a box or casing 2,

which serves as a dust and dirt receptacle.

The-receptacle 2 as shown, is of rectangular formhaving an open top, around which is formed an outwardly-projecting flange 3 and are pivotally mounted in parallel relation between the endsof the box 2, so that they may Specification of Letters Patent.

be swung or adjusted toward and from each other to direct the jets or blasts of air discharged from them at a greater or less angularity, according to the length of the nap or the character ofthe carpet orother surface being cleaned. These nozzles are similar in construction and each preferably consists of a substantially wedge-shaped head 8,- (here shown in the form of a casting,) in which is formed a cavity 9, opening upon one face of the head. .In this open face 10 of the.dis charge head or nozzle is formed a recess 11 to receive a cover-plate 12 and a sheet of rubber or other suitable material '13.

The front or cover plate 12 corresponds in width to the width of thefront face 10 of the head, and the sheet or plate .13, of rubber or the like, is of less width, so that a longitudi nally-extending discharge opening or space 14 is formed between the'lower edges of the plate 12 and the head 8, as clearly shown in Figs. 3 and 5 of the drawings. By using sheets or plates 13 of different thicknesses, so

that the cover-plate 12 will be spaced at a greater or less distance from the face 10'of the head 8, it will be seen that the dischargeopening 14 in the latter may be varied as de-' sired or according to the character of the carpet or other material to be cleaned.- The plates 12 13 may be removably secured in the recess 11- in the face .10 .by screws or similar fastening means 15.

The nozzles 7 are pivotally mounted by providing in their ends tubular trunnions or shafts 16, which extend through bearing-' openings formed in the ends of the box or casing .2 and have upon their outer ends tapered plugs 17. The latter are seated in tapered openings 18, formed transversely air pipes or tubes 19, provided at the ends of, the device. The plugs 17, which turn with the shaft 16 and the nozzles 7, have openings 20, which register with the longitudinal openings or bores in the device 19-- and are retained in the transverse openings 18 by washers and screws 21'.

To cause the nozzles 7 to swing simultaneroq ously, I secure upon their shaft 16, by meansagainst the outer face of the end of the box or casing 2, so as to'firmly secure the two nozzles against movement.

. The pipes 19 have their forward ends closed and their rear ends screwed into inwardly-extending elbows 26, wh 1ch have in their inner ends pipe-sections 27,-1n'wh1ch are provided unions 28. The pipe-sections 27 are screwed into the opposing branches of a T-coupling 29,which has formedintegrally with it an attaching-bracket 30. The atter is securedby screws or other suitable fasten of supply for the air or other gas used for cleaning pur oses is adapted to be coupled to ings uponfthe. rear side of thebox or casing 2, and connected to the third branch of the .T-couplin 29 isan air supplypi e 31, which consists short pipe-sections, e ows, and 'a controlling-valvev 32, which may be of any desired form nd construction. A flexible 'pipe leading om an air-pump, a tank of compressed air, or any other suitable source the upper en of the pipe 31, as will be readily understood. 1 p v 4 Surroundingthe nozzles 7, within thebox or casing 2, is' a receptacle 34. This receptafcle, Which'is preferabl .formed of sheet metal,

is ofsubstantially t e same shape as the interior of the box 2 and consists of a surthe box or casing 2 it will be seen that the dust and dirt loosened by the two opposing blasts of air from the nozzles 7 will pass up.

wardly through the space "between-the box and receptacle andover the upper edge of the latter and intoit and the open upper portion the flanged top or upper box) by means of a sur o'un of said box. A surrounding shield or deflector 39 is preferably provided in the upper portion of the box 2 above the upper edge of the side wall of the receptacle. This defiector, as shown, is in theform of an angle metal strip, which isseated upon the upper edge of the box and has aninwardly-projecting portion 40 to deflect thedust downward into the said receptacle.

- In order to strain the air passing into the.

box or casing to permit it to discharge 1 from the same, 1 preferably provide upon the box,2 a bagor sack 41, of canvas or other suitabledabric, which serves as a strainer.-

This bag '41 has its open end secured begig-e13; of'the band 42,'which may 'brjmetal, or any other suitable material. The bag 41 is adapted tobe siipported above the box 2 by a hanger 43, which is preferably in the form of a rod having its lower end detachably and adjustably secured by means of set-screws 44 in sockets 45, provided upon the rear side clampingofthebox 2 and at'its' upper end any-suitable means for supporting the bag. As shown,

:this means consists of providing the upper end of the hanger-rod 43witli a hook adapted to be engaged by a loopor eye providedupon the bag.

To move (permit the box 2 to be conveniently over the carpet .or other surface to be cleaned, I provide alhandle 46? 'Theilatter has a hand-grip '47 at its outer end anda forkedfor bifurcated. portion :48. at its inner end, The arms orlends of this forked .por-

tion of the handle are pivoted, 'asat 49,11 on Elie oeifite {of the ends of the box 2, and t ey ave a- The the foregoing description, taken in connection with the accompanying drawings.

It will be seen that when the valve 32 is open to permit air to be forced through'the supply-pipes and out of the discharge-open- I ings 14 in the nozzles 7 the blasts discharged therefrom will be directed toward or across s ight longitudinal curvature, as- .sh ownl; construction, use, and advantages. of

the invention will be readily understood from each other, so that they meet at the bottom of thenapof the carpet or other material 1 Y being cleaned, and thereby effectively loosen By adjusting and remove the dust therein. the nozzles angularly with respect to'each other it will be seen that .these opposing blasts of air may be caused to meet at different points beneath the bottom 5 of the box or-casing', accordingto the length of the na V too of the carpet-or other material 'to be cleane It will also be noted that by varying the thicknesses of the rubber sheets 13 beneath the cover-plate 12 or" the'nozzle the amount of air dischargedtherefrom may be regulated according to the character of the carpet or other surface to be cleaned.

. Various changes in theform, .p'ropo'rtion, .f

- and the minor details of construction may be resorted to Without departing from the prin-- ciple or sacrificing'anyof the advantages of this inventionas dermed'by the appended claims. I

Having thus described my invention, what I claim as new, and desire to secure by Let'- ters'Patent, is

and comprising a dust-receiver having an opening-in its lower side, pivotally-mounted discharge-nozzles in said receiver above said opening for'discharging air under compress1on through said opening and means to ad 1 s 1.
